Stator Support Tubes support and center the stator inside the converter and lock the stator
from turning when the converter is multiplying torque while the sprag is locked. The inside
of the tube provides a surface for the oil rings on the input shaft to seal, preventing the oil
from coming out of the converter and going directly into the transmission. The front ring on
the input shaft seals and sends the oil through the pump to the cooler. The oil returns from
the cooler to the hole between the rings into the input shaft and is then directed to cool and
lube the clutches, bearings and gear set.
